How to choose the rubber pipes with high wear and consumption such as trucks and farms

 

This time, I mainly introduce the cloth-covered rubber hoses used in places with high wear and tear such as trucks and farms. This article is only a brief introduction to rubber hoses.

 

The inner liner is mostly black, which is the first choice for adding water, breeding and irrigation.

As the name suggests, the cloth sandwich glue is to add cotton or polyester cloth between the inner rubber layer and the outer rubber layer of the hose, or cross the cord layer, which not only plays the role of supporting and anti-discount, but also mainly anti-compression. The greater the pressure resistance coefficient, the greater the number of layers.

 

What should be explained here is that the water pressure of the truck and the pig farm is not large. The real three-layer cloth rubber hose is enough. ), why is it really three layers? Because some merchants make the two ends of the tube into 3 layers for the sake of profit, after cutting the middle, there is actually only 1 or 2 layers of cloth inside.

 

The main components of the hose are natural rubber, tire reclaimed rubber, etc. The advantages of the deep groove and the hose are wear resistance, heat resistance, stretch resistance, good toughness, anti-aging and softness in all seasons. The disadvantage is that due to the difference in quality and price, some rubber tubes will have a smell when they are first used, and there will also be cases where the rubber hand will turn black and discolor. Sometimes the color of the rubber tube is not necessarily bad. Sometimes the outer layer of the test tube is coated with anti-aging material or grease, and it can be wiped with a rag before use.

 

The detailed classification of rubber pipes is very strict, roughly divided into: water pipes, pressure-resistant pipes, oil-resistant pipes, heat-resistant pipes, etc. For example, heat-resistant and oil-resistant pipes cannot be mixed. See specific usage. Sometimes the buyer encounters irresponsible merchants. In the case that the buyer does not clearly state the purpose, they only sell products with high profits, which is also irresponsible to the customer. Compared with plastic pipes, sometimes pressure-resistant pipes and oil-resistant pipes can be mixed.

 

So, now to get to the point, if you want to choose a good pipeline, you need to first understand the water pressure problem. There are often customers who don’t understand how much pressure is and how to calculate it. When the seller asks about the pressure value, they will be at a loss, and they will also encounter difficulties when choosing a test tube. The seemingly professional problem is actually very simple. Let’s explain the calculation of pressure. Under normal circumstances, the water pressure of household tap water is 3-4 kilograms (KG) or 0.3-0.4 megapascals (mpa). If it is a straight-through pump, the water pressure can be calculated according to the head of the pump. The head of 10 meters is 1 kg of pressure, then in the head of 50 meters, the pressure at the pump outlet is 5 kg, the head of 100 meters is 10 meters, and the head of 100 meters is 10 meters. In addition, it is also necessary to understand that when the water pump is installed, it is often connected to the PPR hard pipe, and the outlet pressure of the water pump is the largest. When the water is connected through the hard pipe, the pressure buffer will become smaller, and when the diameter does not change, The water pressure will also drop, so the actual pressure will also drop.
